Valworx 585502 explosion proof 2-piece stainless steel ball valve is used for positioning control of water, air, oil, and other media compatible with the materials of construction. Positioning System provides an accurate valve positioning function whereby the movement of the actuator is controlled by a 4-20mA input control signal. Any change in the control input signal results in a corresponding and proportional change in the position of the ball. The internal microprocessor and closed loop feedback system continuously monitors and maintains accurate valve position. The valve will remain in the last known position with loss of electric power.
The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad. Valworx does not recommend the use of high temperature brackets with explosion proof actuators. Rugged unique integral motor/housing design provides higher torque in a very small package. Actuators certified for UL Class I Div I Groups C & D, and are tested to rigorous UL and CSA standards and certified by CSA.
